A group 39 Americans came to the Kotel last week. Half of them were Jewish. Almost all of the other half were x-ians. They were firefighters from around the United States and when the call came for volunteers to fly to Israel to help with the terrorists' forest fires they jumped at the chance. They did not receive any money for their work.
What happens in the heart of someone that says, "Someone needs my help and even though I have to leave my comfortable life and family here at home, and even though there is a very real life threatening risk, I'm going?"
It's called their "good inclination". G-d bless them.
